[vdr] Compilation issues with recent DVB header files vs libc6

Hi!

Recent DVB driver releases (now in Kernel 2.6.29) cause trouble compiling
VDR (see snippet A below).

The common solution to this seems to be to add a "-D__KERNEL_STRICT_NAMES".

It felt wrong somehow and I didn't liked this, so I tried another
solution, which is to have any libc6 <sys/*> includes appear before the
linux DVB header includes <linux/*>. Doing this only in dvbdevice.c seems
to do the trick for VDR (see snippet B). I works for VDR 1.6.0 as well as
VDR 1.7.4.

I think the root of this problem is caused by the Kernel headers / DVB
drivers changing from asm/types.h to linux/types.h:

-#include <asm/types.h>
+#include <linux/types.h>

How should this problem ideally be fixed? Is my solution (snippet B)
better than using -D__KERNEL_STRICT_NAMES or should the kernel / DVB
driver developers be blamed for this?
